When using melonDS in , the emulator needs a valid dump of this NAND from a real DSi console to fully boot into the DSi Menu or run DSiWare.
Boot directly into the original Nintendo DS or DSi home menu.
If you own a hacked Nintendo DSi, you can use a tool like to dump your NAND to an SD card. This ensures you have a clean, unique file that works correctly with your system settings. 2. Alternatives
This common issue usually indicates a file size discrepancy. The standard DS-mode ARM9 bios file is only 4KB, whereas a dedicated must be exactly 64KB . If your dumper tool only extracted small, standard DS files, rerun the modern melonDS DSi dumper application on your hardware to pull the larger, augmented DSi-exclusive system images. 2. Black Screens When Launching DSiWare
Ensure you have also selected your DSi BIOS files ( bios7i.bin and bios9i.bin ) and Firmware ( firmware.bin ). nandbin melonds
Even with everything set up correctly, you might encounter issues. Here are some common problems and their solutions:
: Launch the homebrew app on your console. It will generate a folder named dsidump on your SD card root containing your decrypted system files.
Since the Nandbin is copyrighted firmware (extracted from a real DSi), we will cover the process without providing direct download links. You will need to dump your own NAND using a homebrewed DSi or find a legally obtained dump from your personal console.

The Ultimate Guide to NAND.bin in melonDS: DSi Emulation Setup
When emulating the DSi, needs to mimic this internal storage to act like a real, functioning DSi console. The nand.bin file is a dump (a virtual copy) of that NAND chip. Without this file, MelonDS cannot launch DSi software, access the DSi Menu, or emulate DSi-exclusive titles. Key Components Required for DSi Emulation: dsi_bios7.bin (System BIOS 7) dsi_bios9.bin (System BIOS 9) dsi_firmware.bin (System Firmware) nand.bin (The DSi NAND Dump) Why Do You Need nand.bin in MelonDS? This ensures you have a clean, unique file
⚠️ : The only legal and recommended method to obtain a nand.bin file is to dump it from your own, personally owned Nintendo DSi console . Downloading these files from the internet is a copyright violation and, in many jurisdictions, illegal.
The homebrew script extracts your system's internal flash memory alongside the matching ARM7 and ARM9 decryption keys. The process adds a mandatory at the offset block 0xFF800 . This block contains the console's unique encryption IDs, which melonDS must have to decrypt and read the filesystem properly.
Because these files contain copyrighted Nintendo code, downloading them from the internet is illegal. The legitimate and safe method to obtain them is by dumping them from your own physical Nintendo DS, DSi, or 3DS console. Prerequisites for Dumping:
While standard Nintendo DS emulation works out-of-the-box or with basic BIOS files, emulating a DSi or running exclusive DSiWare requires a specific internal storage dump. This file functions as a virtual flash memory chip, allowing the emulator to read the console’s built-in operating system, camera features, and exclusive digital games.
